They are so bureaucratic that they're unable to do anything without filling out the proper paperwork first. They have also never taken vacation days. Ernestos are usually seen chatting around the office cooler.
Ernestos are spherical purple robots with black and purple limbs, a black spherical head with a cycloptic eye, and a black tie paired with a matching top hat.
- Office/Business-themed attacks: Ernestos are able to use attacks based around office work.
- Ball form: Ernestos have the ability to roll around in a ball form. They enter this form by retracting their head and limbs.
- In "Let's Be Friends", when K.O. was sneaking round Boxmore dressed as a robot and making beeping sounds, a pair of Ernestos asked each other "Should I be offended?" in reference to racial stereotypes and old depictions of sci-fi robots.
